Used this bag over the past year and I have found that around 20-25 degrees F. it gets a little cold, almost chilly, which I expected as it is a thirty deg. bag. I put a pair of thermal underwear on over the length of my legs and I was fine. But the bottom of the bag was cold even on top of a Therm-a-rest trail pad which translated into lower back pain. I understand that I should have had a thicker pad and a lower rated bag. I am fully satisfied with all Marmot bags I have tried. This is a great bag above 30 degrees F. and very compresable to about a 11" ball.
